Temporary keratoprosthesis for surgical management of complicated combined anterior and posterior segment injuries to the eye: combat- versus noncombat-injury cases.

We used a Landers-Foulks temporary keratoprosthesis lens to combine penetrating keratoplasty with vitreoretinal surgery in 21 eyes of 21 patients. Ten of these patients were victims of combat injuries; 11 had traumatic injuries unrelated to war. After a mean follow up of 11 months, satisfactory overall results, ie, an attached retina and a clear cornea, were obtained in nine eyes (42.8%). In two, the retina was attached but the corneal graft was rejected. Eight eyes achieved a visual acuity of 5/200 or better. The visual prognosis as well as the rate of retinal reattachment for the combat-injured eyes were poorer than those for the traumatic noncombat-injured eyes. At the last follow-up examination, 60% of the combat-injured eyes were considered visually lost, as compared with 36.3% of the noncombat-injured eyes.
